As shown in Figure REF , RID=7876 (\(F775W\) =26.85) and RID=9944 (\(F775W\) =26.49) are located within 06 each other. Because of the limited spatial resolution of MUSE, a MUSE source (MID=103, \(z_{\rm s}=2.99\) , ZCONF=3), which shows \(\mbox{Ly$\alpha $}\)  emission and absorption depending on wavelength and position, conservatively has two HST counterparts of RID=7876 and RID=9944. The \(\mbox{Ly$\alpha $}\)  absorption feature gets stronger at the position of RID=9944 than that of RID=7876RID=7876 and RID=9944 are treated as a single HST source in the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey [1]} and 3D-HST [2]}. Following the other MUSE GTO papers, we used the catalog of [3]} as a HST prior list (see also Figures REF  and REF ). Moreover, MID=103 is also within 06 from RID=7847 at \(z_{\rm s}=3.00\)  (\(F775W\) =26.84, ZCONF=3). Near them, we can see an HST non-detected source at \(z_{\rm s}=3.00\)  (ZCONF=2, MID=8246) and a potential neighbor of RID=7758 at \(z_{\rm p}=2.89\)  (\(F775W\) =28.20). These sources are also included in an overdensity of MUSE-detected LAEs, "G01" [4]}. As a conservative choice, we categorized RID=7847 as a nonisolated galaxy, in addition to RID=7876 and 9944.
